Subject: [PATCH rcu 02/21] srcu: Fix s/is/if/ typo in srcu_node comment
Date: Mon, 18 Apr 2022 17:03:03 -0700 [thread overview]
Message-ID: <20220419000322.3948903-2-paulmck@kernel.org> (raw)
In-Reply-To: <20220419000315.GA3948789@paulmck-ThinkPad-P17-Gen-1>
This commit fixed a typo in the srcu_node structure's ->srcu_have_cbs
comment. While in the area, redo a couple of comments to take advantage
of 100-character line lengths.
